SPECIFICATION forming part of Letters Patent No. 527,192, dated October: 9, 1894.

Appli ati n filed April 21, 1894- Serial No. 508,458- (No model.) i

To all whom i2? may concern: I

Be it known that we, ONWARDBATES and GILMA W. SMITH, of Chicago, Illinois, have invented certain new and useful Improvements in Cattle-Guards for Railways, of which the following is a specification.

Our invention relates to guardsfor preventing cattle from straying upon railway tracks fromroad crossings and similar points.

The invention consists in a series of wooden slats whose tops are wholly or partly surfaced with metal strips having blunt teethfproject' i ng upward from them to destroy the footing of the cattle; also incertain matters of detail tial end view on an enlarged scale.

as hereinafterset forth.

In the accompanying drawings, Figure l is a plan View of a railway cattle guard with our invention applied to it. Fig. 2 is a parperspective viewof one of the su rfacing strips. l are the track rails and 2 the ties. 3 are wooden slats which when in place are ordinarily placed parallel with the rails and fastened down to the ties. On the top of each slat is a metalsurfacing strip 4: with blunt teeth projecting up from its edges as at 5.

These strips 4 are of flat rolled steel with the teeth struck up from the body of the strip at the edges as shown in Fig. 8. It is not necessary that the strips 4 extend the entire length of the slats but they may cover only a portion of the slats as, for example, in Fig. 1.

6 are spacing thimbles between adjacent slats and 7 are bolts extending through the of slats together into a guard section. It is obvious that the parts of the guard. may be variously modified without departing from the invention. i

VVeclaim i t 1 In a cattle guard the combination of wooden slats and metal surfacestrips comslats and the thimbles and binding a series posed of flat steel bars with blunt teeth struck stantially as set forth, of a series of wooden slats, and a series of metal strips, with teeth projecting upward at their edges, covering a portion only of the tops of the slats. p

4. Ina cattle guard, the combination substantially asset forth, of a series of wooden slats, and a series of metal strips with upward projecting teeth thereon, covering a portion only of the tops of the slats.
